JOSEPH GAVTHRA, OF ROCHESTER, NEW YORK.

CORN-HUSKER.

Specification of Letters Patent No. 18,571, dated November 10, 185'?.

To all whom t may concern:

Be it known that I, J osEPH OAWTHRA, of the city of Rochester, in the county of Monroe and State of New York, have invented a new and Improved Machine for Husking Indian Corn; and I do hereby declare that the following is a full and exact description of the same, reference being had to the accompanying drawings and to the letters of reference marked thereon.

The nature of my invention consists in constructing two or more rollers to run in juxtaposition with one or more grooves in each, running laterally, and so as to meet in revolving, for the purpose of clasping the ears of corn.

A fine saw or bladed wheel is provided to run at the ends of the rollers where the butt of the ear is placed which for the sake of convenience is the outside in my machine. An' endless belt is provided to revolve around two centers or over two rollers by which the belt is stretched along the lower part of the machinery; upon which belt the corn is dropped by the grooved rollers when the butt is `properly'cut and carried along by the belt under a grating of coarse wire or rods running laterally with the ears of corn and while the ears are thus carried along under such grating a revolving wheel called the husker with teeth projecting a suiiicient distance tears up the husks from the tassel end and brings them within the sphere of another wheel called a curved toothed fan which seizes the husks thus l loosened and started and clears the ear entirely from husks and all its covering and they fan of the wheel cleans the ear and drives the husks and all the refuse matter out of the machine; while the ear goes on upon the belt and is deposited at the end opposite from that at which it entered.

To enable others skilled in the art to make and use my invention I will proceed to describe its construction andoperation.

I prepare a framework of wood or iron of any convenient dimensions as represented in Figure l at a On one side I place a driving wheel B which by cogs meshing into the cogs of c propels a shaft d running at right angles with the drivingwheel a belt from a pulley aflixed to the inside part of the aXle of the driving wheel propels the wheel F.

h is a wheel which drives the wheel I into the extended cogs of which it meshes and has a long axle around which as one center the belt 79 revolves. The wheel I meshes also into the wheel J and the wheels I and J are aiiixed to the aXle of the rollers (t Z 7 C m and n are spiral or elastic spring disks (the spring being behind the disk) by which the pressure is adjusted to the different dimensions of ears.

0 Fig. 3 is an inclined table to facilitate the feeding of the machine.

7J represents the belt as it comes around the axle of the wheel L which last mentioned wheel the belt p propels. This belt is plainly shown in Fig. 3 at p e is a cog wheel which propels the fan and is plainly represented in Fig. 3 at e g is a mere covering to the fan which may be thrown back as in Fig. 3.

71 represents the position of a spiral or elliptic table or platform on which the upper part of the belt passes and is kept pressed against the grating by the table or platform for the purpose of keeping the ears of corn firmly and regularly in their places and compelling both large and small ears to roll over and over as they pass from rod to rod in the grating.

The table and spring are represented in Fig. 2 at r upon the outside of the belt p I fasten halfrounds of wood at convenient distances apart which as they crowd by the ears of corn roll them over and pass them along from space to space between the rods each halfround moving each ear the distance of one round in the grate-this rolling process loosens the husks, makes the labor lighter and forwards the ear to the place of depositthe saw or edged wheel 4 is propelled by a belt from a pulley at the end of the shaft cl.

Fig. 2 is a section cut transversely through the fan.

In Fig. 2 l represents the armsof the fan 2 a section of the husker 1^ the spring table g the cover of the fan cut transversely 3 7 the plane and opening apron and at which the husks and dirt are discharged.

Fig. 3 represents a section of the fan, the husker a 2, the belt with halfrounds, the saw or edged wheel il sections of the rollers Z and 70.

Fig. et represents the grating, 3 3, the husker 2 2 and a part of the belt C p.

When the driving Wheel B is put in motion the shaft d and the Wheel F7 are driven, the belt p which runs around the axle of the Wheel F drives the Wheel 71, Which in its turn drives I and I drives J. The pulley at the end of the shaft d drives the saw or edged Wheel 4 in Fig. 3 and the Wheel E as seen in Fig. 3 drives the fan, and a belt from a pulley upon the inside of the axle of the fan extending to the axle of the husker drives the huslrer.

The teeth of the husker are made short and the husler runs With great Velocity. They take up the husks from near the end of the ear and place them Within reach of the fan. The fan consists of curved arms with teeth upon cross plates at the perimeter; the curved arms giving to the plates and teeth a curved form and fit them to take husks and strip the husks lengthwise of the ear and from the tip to the butt.

The fan is made to run so near the husker as to keep the husler clean, and the speed of the fan and the tattered condition of the husls when taken by it, prevents any clogging in the fan. The force of theJ fan and the violent current of air produced throws all the husks and refuse matter out of the machine with great facility and keeps the machinery at all times free and in Working order.

`What I claim as my invention and desire to secure by Letters Patent is- The grooved rollers l Z0 sa7 Wheel 4L and endless apron p in combination with the husker 2 grating 3 and curved toothed fan l the Whole being constructed substantially as herein set forth.
